It documents the major line items of work the Government expects to see accomplished, but it does not attempt to explain the exact details and/or method of execution for requirement; the Contractor will be responsible for providing specific performance details in their proposal. The Contractor must comply with all provisions and requirements of this contract.

STATEMENT OF NEED

1 BACKGROUND: This project is located at Building 8999, located on the car path to the north side of North Beale Road, Beale Air Force Base, California (See Attachment 1 – Site Map for exact location). Well #9 does not have a sanitary/annular seal, which is required by Department of Water Resources (DWR) Bulletin 74, California Well Standards. It was originally constructed in 1966, Sump pump installed in 2015 and Minor repair and clean off occurred in 2017. Well #9 is approx. 354 ft deep, its static water level is 108ft, with 2500gpm pump rate.

Well, is situated in undeveloped site, surrounded by perimeter fencing with adequate space for the planned project. Refer to the site plan and photo log attached.

2 PROJECT GENERAL SCOPE: The intent of this project is to replace Well #9 and connect the new well to the existing electrical, communications and piping network. The project will include all work necessary to Design, drill, install, develop, equip, test, and properly functional according to the requirements provided. Well #9 is a community water supply well as defined by the Section 13710 of the Water Code and the planned replacement well must meet standards for a community water supply well.

3 ITEMS OF WORK: Work includes but is not limited to the following items:

3.1 Plan/Permits

3.1.1 Contractor shall provide 100% and final IFC after review phases of design for the project using the standard applicable requirements listed below and to show the surface structures (existing/new), equipment, connections, sections to show the details of the underground installations, and dimensions of the new well and relative installation. design must also clarify the environmental protection measures according to the applicable requirements given.

3.1.2 Permitting; Provide all permits required. A well permit from the Yuba County Environmental Health Department is anticipated for both well destructions. And well installation. Acquiring the permits will need a water well installation plan to satisfy Yuba County and scope relative UFGS -33 11 13 requirements.

3.1.3 Submit a water and spill discharge plan to 9CES/CEI for approval prior to start of construction. Elements for the plan can be observed from AF-813 attached.

3.1.4 Perform a pre-drilling site inspection to identify location for new well, identify the existing underground utilities, and arrange for environmental limitations to prevent damages while digging.

3.2 Construction.

3.2.1 Properly abandon and seal the existing Well #9 including demolition of concrete, piping, casing, wires, pump, and all relative removable elements and dispose them off base, by following the Environmental/permit regulations and available Local, Federal, and State requirements.

3.2.2 Install new water well, pump, and control system with industry standard casing to a sufficient depth capable of maintaining flow of 1,200 gallons per minute (GPM) and connect to the existing drinking water supply piping network. Well installation shall be completed by a State of California C-57 licensed drilling contractor.

3.2.3 Provide borehole and well construction log.

3.2.4 Casing. The new water well casing shall be steel construction as defined in the

California DWR well standards. Screen perforations shall be selected in conjunction to filter pack design, to maximize well production and minimize infiltration of filter materials in well.

3.2.5 The existing well fittings are under the 100-year flood level, surface completion of the well shall be installed to the level of the existing transformer pad. The intent of this requirement is to eliminate the possibility of surface water entering through well head.

3.2.6 Provide new reinforced concrete pad estimated to be 6 feet by 10 feet by 4 inches thick.

3.2.7 Well shall conform to all local, state, regional and federal requirements for a community drinking water supply, including sanitary/annular seal to a minimum required depth not less than 50 ft.

3.2.8 Furnish new downhole water level sensing equipment to be connected to Siemens automated system.

3.2.9 Provide industry standard well testing to show the well meets the minimum requirements for production rate and water quality.

3.2.10 Paint the new and existing piping according to the submittal approved by base civil engineer.

3.2.11 File well construction and well destruction reports with the DWR.

3.3 Electrical

3.3.1 The well system will be powered by existing underground electrical system that feeds by a 225 KVA, 3 phase pad mounted transformer.

3.3.2 The existing generator at well #9’s house must be tested to be prepared as an emergency power resource.

3.3.3 Provide and install new 75-Hourspower submersible well pump, wiring, Pump controller (VFD) and associated parts and equipment.

3.3.4 Install a new water flow meter.

3.4 Connections and Valves

3.4.1 Modify existing piping as required to connect with new well. All piping shall meet appropriate code requirements and at a minimum shall match existing systems.

3.4.2 Provide new automatic valve “CLA-VAL” or similar automatic valve for water supply piping and flush piping. Reconfiguration of the piping, relocation of the existing check valve (if needed) and requirements for the new cla-valve must be clarified within the design.

3.5 Fencing

3.5.1 Contractor shall remove existing fencing around well piping and foundation, keep fence caps for re-use.

3.5.2 Contractor shall install new chain link fencing, posts, and barbed wire topping around new well, associated piping and new transformer.
